Hi Adam,

Hope you are fine~

For your question of the long-term tensile strength, I checked with our product Dept. The specification is correct and we can provide the long-term tensile strength with 1200N, hope you know that.

Maybe drop cable can go farther than I thought.
I guess I still don't understand why the Corning drop cable with a pair of fiberglass rods down the side can handle 400N while the FS drop cable with a pair of fiberglass rods down the side can handle 1200N.  Is the strength member not the limiting factor?  Is Corning just being more conservative than FS?

If you hang the drop cable too far, what failure actually occurs?

That fiber glass central strength member is pretty strong.  I think you could use it as a tow rope.

My guess it will not be much different strength than corning drop.
FS does make some drop with steel wire reinforcement, I'm not sure if that would be any better because of the higher weight.

    This cable at FS:

    Their web page is saying long term tensile strength of 1200N.
    Corning ST drop cable has a similar type of strength member and
    they say
    400N.

    At 1200N it would appear that I could hang that cable 600 feet
    with a 1%
    sag and I'd still be within strength limits.

    So is this a lie like the horsepower on a shop vac, or could they be
    using some alternate but valid way of measuring tensile strength, or
    could it actually be correct?

    I sometimes pretend I'm an engineer, but I'm wondering if any of you
    real engineers out there have any insight.

    Thanks,
    Adam
